plzz solve this plzz it's urgent

Answer 1

HEYA!!!!!

Here is your answer :
_______________________________

From RHS :
=========

$\frac{1 - \sin}{1 + \sin } =$

Rationalize the denominator.

$\frac{1 - \sin }{1 + \sin } = \frac{1 - \sin}{1 + \sin } \times \frac{1 + \sin }{1 + \sin} \\ \\ = \frac{ {1}^{2} - { \sin }^{2} }{1 + { \sin}^{2} } \\ \\ = \frac{ {(1 - \sin) }^{2} }{ \ { \cos}^{2} } \\ \\ = \frac{1}{ { \cos}^{2} } - \frac{ { \sin}^{2} }{ { \cos }^{2} } \\ \\ = ( { \cosec - \tan) }^{2}$

Therefore, RHS = LHS

Hence proved....
